Application filed Rovember 8, 1828. Serial Railing This invention relates to gaskets of the character adapted for use as packing around refrigerator doors, as a weatherstrlp for doors, windows, etc., and for various other uses where a seal is required.

One of the objects of this invention is to rovide a gasket in which a roll of soft fibrous material is closely confined by an envelope of flexible waterproof fabric which is extended to provide a tacking lap, but .in which the tacking la is reinforce and secured in a simple an effective manner.

Another object is to provide a gasket of the character described which is simple in construction, effective in its action, neat in appearance, durable and economical toman ufacture.

Further objects will appear from the detail description taken in connection with the accompanying drawing in which Figure 1 is a section through a door and its jamb illustrating the application of the gasket embodying this invention,

Figure 2 is a view showing the method of applying such a gasket when turning corners.

Figure 3 is a rspective view showing one embodiment 0 this invention.-

Figures 4 and 5 are similar views showing other embodiments of this invention.

Referring to the accom anying drawing and more particularly to igure 1, A designates a gasket which is arran d for place ment between the door B an the jamb C, as for instance is used in a refri rator. The gasket has a tacking la D rou h which fasteners, such as tac s 1 may passed to apply the same.

Referrin' to Figure 3, the gasket comprises a re 1 2 of soft fibrous material such as cotton, and enclosed by an envelope 3 of flexible waterproof material such as-rubberized cotton. In Figure 3 both free edges of the envelope are extended, as shown at 4, to provide a tacking lap, and an inside line of stitches 6 passes through the fabric plies along the roll and is adapted to closely confine the same in order to provide a tight but yielding packing which will freely yield to form an-eifective seal and when :essure is relieved will return to a circular shape. A fabric reinforcement 10 is doubled over the tacking lap, in this specific embodiment,

one of the plies of the tacking lap, so that one of the plies of this reinforcement will lie between two' plies of the taclnng lap;

.cluded within the both edges of the reinforcement 10 are in-- In turning preferably alsotheinside edge ofthereinforcement is enclosed within and is secured at its edge by the inside line of stitches 6.

A line of stitches 7 passes through the fabric plies along the outer edge of the tacking a stiffen the structure and plies between the lines of stitc es 6 and 7 In; Figure 4 one of the lap 1s extended onl su cient as to be in:

ine ofstitches '6 while eluded within and secured by that line of stitches 6. In Figure 5 both fabric plies 4 are extended the full width of the tacking lap and both edges of the reinforcement 10 are included within and secured by the insideline of stitches 6.-

In the application of this gasket the fasteners 1 pierce the tacking up and secure the gasket in lace and in view of the fact that this tacking lap is reinforced by the fabricreinforc'ement 10- as well as by the lines of stitches, not only will this tacking lap be stiffened transversely but also longitudinally, so that not only is buckling revented but the tackin lap will be strengt enin order to" close the sameas well as to a revent buckling] I Addit onal stitches 8 pass t rou hthe fabric liesof thetacking V ed in its own plane. his is of particu ar ad- 7 vantage inv view of the fact that the securing fasteners are applied onl at intervals so that the reinforcement 0 between the fasteners is of articular utility. corners, as s own in; Figure the tacking lap" 2, the tacking lap is cut or notched, as shown at 9,'Figure 3, so as to permit such a turnin and the lapped portions can then be secure by a fastener, as shown in Figure 2. The

provision of the inside line of stitches 6 not p onl permits the notching to be accomplished while still retaining the roll tight at the point of turning but the additional stitches,

more particularly the stitches] 8, revent bucklin and maintain the tacki ap flat and tig t. By employin a rein orcement and more especially a fol ed reinforcement, which is a separate piece of fabric a plied and folded over the tacking lap, not only can the saine be more readily applied, but crimping and buckling of'the reinforced tackin lap is avoided so that the desired reinforced but fiat tacking la is secured. The construction shown in igure 4 is particularly 'comparatively thin but strong tacking ap licable for smaller too thick; for a lap is secured by the provision of the stitches along. the tacking lap which reinforce as well as stiffen the same. The construction shown in Figures 3 and 5 are particularly applicable to larger gaskets where the tacking lap can be more substantial and is referably so in order to rovide for additional stren h as well as sti ness.

It is obvious that various other changes ma be made in the details of construction wit out departin from the spirit of thisinvention; it is, t erefore, to be understood that this invention is not to be limited to the specific details shown and described.

Havin thus described the invention what is claime is:

1. A gasket comprising, a roll of soft fibrous material, an envelope of flexible waterproof fabric enclosin said roll and extended to provide a tacking lap, an inside line of stitches passing through the fabric plies along said roll and adapted to confine the same in order to provide a' tight but yielding packin and a separate fabric reenforcement doub ed over sald tacking lap and having one of its edges secured by the inside line of stitches. 1

2. A gasket comprising, a roll of soft fibrous material an envelope of flexible water roof fabric enclosing said roll and exten ed to rovide a tacking lap, an inside line of stitc es passing through the fabric plies along said roll and ada ted to confine the same in ordgrto provi e a ti ht but yielding packing, and a separate fa ric reinforcement doubled over said tacking lap and having both of its edges secured by the inside line of stitches.

3. A gasket comprising, a roll of soft fibrous material, an envelope of flexible water roof fabric enclosing said roll and exten ed to provide a tacking lap, an inside line of stitc es passing through the fabric plies along said roll and ada ted to confine the same 1n order to provi e a.ti ht but yielding packing, aseparate fabric reinforcement doubled over said tacking lap, a line of stitches passin throu h the fabric plies along the outer e ge of the tacking lap and means securing the fabric plies between the lines of stitches ,adapted to reinforce the tacking lap.

\ 4. A gasket comprising, a roll of soft fibrous material an envelope of flexible water roof fabric enclosing said roll and exten ed to lprovide a tacking lap, an inside line of stitc es passing through the fabric plies along said roll and ada ted to confine the same in order to provi e a ti ht but yieldin packing, a separate fabric re1nforcement oubled over said tacking lap, a line of stitches passin throu h the fabric plies alon the outer e e of t e tacking lap and stitc es passing t rough the fabric plies between the lines of stitches substantially as and for the purpose set forth.

5. A gasket comprising, a roll of soft fibrous material, an envelope of flexible waterproof fabric enclosing said roll and extended to rovide a tacking lap, an inside line of stitches passing through the fabric plies along said roll and ada ted to confine the same 1n order to provi e a tight but yielding packing, and a se arate strip of fabric secured over said tac ing lap to reinforce the same, L

In testimony whereof I afiix my signature this 4th day-of October, 1926.
